You just finished a run on a warm day and you're hot, tired, and thirsty. Of course you could reach for your favorite neon-hued sports drink, and there's nothing wrong with that. But runners often forget all the other options out there. In fact, research has shown that plenty of other types of beverages (some of which may already be in your refrigerator) have their own healthful qualities and can help you stay hydrated before, during, or after your run.
"Mother Nature has given us a huge range of healthy drinks," says Molly Kimball, R.D., a sports dietitian at Ochsner Elmwood Fitness Center in New Orleans. "They're refreshing and can recharge muscles and benefit performance." And (most important) they taste good, too.
Iced Green Tea
When: Pre- or postrun and on easy runs less than an hour
Why: Green tea is a stellar source of catechins, antioxidants that fight heart disease and cancer. According to research, catechins can reduce muscle damage caused by exercise, and also speed recovery. A recent study found that people who had the equivalent of five cups of green tea daily for three months and exercised lost more belly fat than those who only exercised. Iced green tea is a tasty alternative to water on easy, short runs, says Leslie Bonci, R.D., director of sports nutrition at the Pittsburgh Medical Center. Plus, tea contains caffeine, which boosts speed and endurance. If you drink iced green tea often, go with unsweetened, says Kimball, to avoid taking in excess calories.
Sipping Points: Steep tea bags for at least three minutes to release more catechins. If you buy bottled, choose brands with fewer than 15 grams of sugar per eight ounces.
When: Pre- or postrun or on runs of about 60 minutes
Why: Coconut water, the clear liquid found inside the fruit, contains none of the fat found in coconut milk and has a tangy, light almond flavor. Eleven ounces contain 14 grams of sugar and 670 milligrams of potassium-way more than sports drinks. "Potassium works closely with sodium to maintain water balance and helps trigger muscles to contract and relax optimally," says Suzanne Girard Eberle, R.D., author of Endurance Sports Nutrition. Coconut water has enough carbohydrates for an hour-long run but not enough sodium for longer efforts.
Sipping Points: Coconut water, which is fat-free, comes plain or flavored with mango, orange peel, or passion fruit.
Why: The drink you loved as a kid has the ideal amount of carbohydrates and protein that tired muscles need for recovery, says Joel Stager, Ph.D., director of the department of kinesiology at Indiana University. According to a study Stager led, drinking chocolate milk postexercise speeds up recovery and increases the time it takes to reach exhaustion during a subsequent exercise session better than sports drinks. And a 2007 British study found that regular milk is better than water or a sports drink at restoring fluid levels following a bout of exercise in the heat. Plus, milk contains bone-strengthening vitamin D and calcium.
Sipping Points: Single-serving containers are handy for tossing into a cooler for a postrun treat and for portion control.
